' EARL E. EIGKIVIEYER, F DAYTON, OHIO, ASSIGNOR TO THE COMPANY, OF DAYTON, OHIO, A CORPORATION Patented Apr. 26, 1932 UNITED STATES PATENT OFFICE DAYTON PUMP, & MFG. OF OHIO GASOLINE PUMP Application filed October 31, 1928. Serial N0.' 316,246.

My invention relates to gasoline pumps.

It is the object of my invention to provide a gasoline dispensing pump in which it is impossible to move the handle, which sets the quantity of gasoline to be dispensed, while the dispensing operation is taking place.

It is a further object to provide a pump in which the valve controlling the delivery of gasoline from the visible container to the automobile is locked against being opened until the handle of the setting mechanism is in operative set position.

It is a further object of my invention to provide means of limiting the upward and downward movement of the measuring tube.

It is a further object to provide a single unitary manifold for use in connection with a measuring tube which is operated by the setting mechanism and the overflow so that no more than a predetermined quantity of gasoline can be delivered to the visible con tainer.

It is a further object of my invention to provide an interlocking system so that, when the setting mechanlsm for settlng the delivcry of a given quantity of gas is placed in the draining position, it will then be possible to place the delivery hose in the drain-back passageway and, when the hose is locked in such passageway, the action of locking will simultaneously unlock-the drain valve in the hose which, up to that time, has been locked against movement.

It is a further object to provide for unlocking the mechanism which has locked the hose lock in inoperative condition, such unlocking of the lock taking place by the passing of the setting rack into its lowermost position.

It is a further object of my invention to provide a sight drain in the delivery line from the visible container to an automobile so that all of the gasoline passing through the pipe can be seen.

It is an additional object to provide a stop interposed betweenthe supply pipe and the locking pin on the setting mechanism so as to prevent the operation of the lock when it is in set position.

t 15 a further OlOJGCt to provide a unltary' C pump so arranged that the pumping mechanism is carried on the cast iron base and the setting mechanism, together with the sump casting and the bowl of the visible container, are all carried on a supplementary structure mounted upon the base but. independent of the pump, while the casing for the pump is purely a casing without any structural function.

Referring to the drawings in detail, 1 is a base upon which is mounted conventional pumping mechanism of any desired character designated 2 operated by the segment 3 from the handle 1 which in turn operates the rack 5\ Gasoline from an underground container is pumped up through the supply pipe 6 this pump;

This supply pipe terminates at its upper end. adjacent the bottom 7 which carries the visible bowl of glass designated 8. A unitary casting containing a sump is provided with a sleeve 9' and a gasket 10 for accommodating theupper end of the supply pipe 6. The gasket 10 is held yielding-1y in place by the gasket follower 11 which is spring pressed by the springs 12 suspended on the pins 13 that are carried on the sleeve 9.

A second supply pipe 14 isthreaded into this casting; 9 and extends into the visible bowl 8. Itdelivers the gasoline over the top of this pipe 14 beneath a spaced dome 15 carried thereby.

Gallon indicators 16 are mounted upon a supporting rod 17 within the bowl 8, the lower ends of the rods 17 being mounted upon the floor 7 of the bowland carried from the top 18' thereof. This top 18 is provided with aglass window 19 so that the electric lamp may illuminate the interior of the bowl 8. The electric l'a-mp is designated 20.

As will be seen in Figures 9 and 27 the sump casting is provided with a chamber 21 inwhich slides a measuring tube 22 that may be moved into position in the glass bowl 8 according to the measurement desired so that the gasoline, the height of which is indicated by the height of the tube 22, may be measured and flow from a bowl 8 upon the lower ing of the tube 22 to the position shown in Figure 27. This tube 22 is mounted upon a rod 23 known as the measuring rod. It is connected by a spider 24 to the tube 22 so that the gasoline can flow back through the measuring tube around the spider into the chamber 22 in which the measuring tube telescopes. The spider 2 is formed on the lower end of the tube 22 by forming therein, on each side, a slit 22a. The parts of the walls between this slit and the lower end of the tube are pressed in, as shown in Figure 8, to form the parts of the spider. The inner parts of the pressed-in walls engage the rod 23- and are fastened thereto by rivets, or any other suitable means.

The gasoline flows down through the bottom of the tube 22, thence upwardly through the tapered passageway 25 whence it passes over into. the horizontal passageway 26 into the delivery pipe 27 through the sight flow glass 28 past the hose drain valve 29 and into the hose 30. Also connected to this sump casting is the overflow tube 31 which is so arranged that any gasoline in excess of the total quantity which can be safely placed in the container will drain back into the reservoir below the pump. This pipe 31 therefore is mounted in. the upper end of the casting at the point indicated at 32 so that the gasoline flowing; back through it will pass down through semi-circular passageway 33- to the bottom of the casting and thence in a semicircular path through the passageway 34 into the drain back pipe 36, all as indicated by the arrows.

The bottom of the sump 25 is also provided with a sump drain 37 for independent drainage.

38 is an air inlet line that communicates with the passageway 26 and. with the bowl 8.

The sump casting is attachedto the bottom 7 of, the bowlby the bolts 39. The bowl itself is provided with a cover lO which is adapted to carry in the rim 41 a suitable glass device for advertising purposes, which is not illustrated, as it forms no part of this invention.
